Dispenser closure



May 10, 1938. J R RING DISPENSER CLOSURE Filed Aug. 11, 1937 James 2?. 92/ 2 ATTORNEYS Patented May 10, 1938 UNITED STATES PATENT OFFICE Application August 11,

2 Claims.

The invention relates to a dispenser closure and more especially to a self-closing nipple or nozzle and cap for a container.

The primary object of the invention is the provision of a device of this character, wherein the same when in association with a collapsible container or tube or the like will function as a selfclosure therefor and through pressure similar to paste tubes will enable the dispensing of the content thereof through pressure of such content on compressing the container or tube and will automatically seal or close the said container or tube when the pressure is relieved or released therefrom, the closure being of novel construction.

Another object of the invention is the provision of a device of this character, wherein the dispensing nipple or nozzle is normally coiled within a cavity which is capped, the latter and the nozzle or nipple being extended under the content of the container or tube when under pressure for the dispensing of such content.

A further object of the invention is the provision of a device of this character, which is simple in its construction, thoroughly reliable and eificient in operation, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a side elevation partly in section of a collapsible container or tube showing the closure constructed in accordance with the invention applied.

Figure 2 is a fragmentary vertical longitudinal sectional view showing the dispensing nipple or nozzle extended and the cap associated therewith in open position.

Figure 3 is a fragmentary vertical longitudinal sectional view through the nozzle or nipple when 45 in straightened position.

Figure 4 is a vertical longitudinal sectional view through the nozzle or nipple and the cap, the nozzle or nipple being in a straight condition.

Similar reference characters indicate corre- 50 sponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a metallic collapsible container or tube of that kind used with tooth paste or other content and has formed at the discharge end there- 1937, Serial No. 158,569

of a mouth housing 5 forming a cell or compartment 6 opening through the outer end of said housing and closed by a cover 1 hinged at 8 to the said housing.

Fitted within the neck 9 between the tube A and. the housing 5, the said neck being contracted, is the base end ll] of an extensible dispensing nipple or nozzle II which is of elongated formation and having its dispensing passage I2 opening through the outer end thereof. This nipple or nozzle H has formed therewith intermediate of its length the protuberance l3 extending from the inner face of the cap I for a purpose presently described.

Located within the nipple or nozzle H is a normally coiled spring wire 14 having the inner forked end l5 anchored to the base ID of the said nipple or nozzle and this wire is effective for the coiling of the nipple or nozzle under normalcy within the compartment or cell 6 interiorly of the housing 5. The normal coiled condition of the nipple or nozzle ll eifects the closing of the cap 1 for covering the outer open end of the compartment or cell 6 formed by the housing 5.

When it is desired' to dispense the content of the tube A, it is necessary to exert a pressure upon the latter from the exterior thereof thus placing the content under pressure so that it will flow into the nipple or nozzle I l and through such pressure the said nipple or nozzle II is straightened and under the straightening thereof the cap I is swung to open position. The pressure of the content of the tube A within the nipple or nozzle causes the latter to spread so as to avoid the spring l2 which has automatically straightened from choking the nipple or nozzle and such content will be discharged therethrough. When pressure is relieved from the content of the tube A, the spring wire it through inherent resiliency or contraction will coil the nipple or nozzle ll drawing it within the compartment or cell 6 and at the same time automatically closing the cap I on the outer open end of said housing 5.

The base I0 of the nipple or nozzle H is anchored in the neck 9 between the tube A and the housing 5, as at Hi. This nipple or nozzle H is preferably made from rubber rendering it flexible for the extending and coiling thereof under pressure and the spring wire [4, respectively.

What is claimed is:

l. The combination with a collapsible tube or container having an open mouth housing, a flexible dispensing nozzle fitted in the mouth housing, and a normally coiled spring element fitting the nozzle and coiling the latter within the mouth housing.

2. The combination with a collapsible tube or container having an open mouth housing, a flexible dispensing nozzle fitted in the mouth housing, a normally coiled spring element fitting the nozzle and coiling the latter within the mouth housing, and a cap carried by the mouth housing and connected with the nozzle for opening and closing on the extending and coiling of the latter.
